As a leader in the field of engineering projectors, Epson has recently launched a new line of laser engineering projectors for a variety of environments.
The scened experience of engineering projectors is extremely important, and only with a superior scene-based application experience can meet the demanding requirements of enterprise customers. Epson laser pointer engineering projectors have a compact laser source, reflective fluorescent wheel, 5000/6000 lumens color brightness and so on.
Based on the innovative reflective fluorescent wheel design, Epson's new products have higher light source utilization efficiency; with compact laser components, the series of laser light sources output the same brightness in a smaller volume, with a color brightness of 5000/6000 lumens.
In addition, Epson laser engineering projectors are designed according to different color brightness. There are 6 products in two sub-series, which are CB-L500/L500W/L510U models with 5000 lumens brightness and 6000 lumens. CB-L610/L610W/L610U models.
Recently, a Swiss research team used existing terahertz spectroscopy to measure the hydrogen bonding of liquid water. The work carried out using this technology may help explain the special nature of water in the future.
The researchers used ultra-short visible laser pointer pulses to excite dye molecules dissolved in water, thereby changing their charge distribution. Subsequently, the terahertz pulse measures the reaction of the surrounding water molecules. The relatively low frequency terahertz spectroscopy allows researchers to analyze the forces that exist between water molecules. Observing the forces between these molecules can help researchers understand the anomalies of water, because the hydrogen bonds in liquid water molecules constitute many unexpected properties of water, such as water at 4 ° C, the highest density.
Because the terahertz spectrum of a liquid like water is very wide and extremely blurred. This makes it difficult to extract information from it. The time-resolved techniques used in the latest research may overcome this limitation. Next, the researchers plan to use this method to explore the structural and dynamic mechanisms of water that is still in liquid but below freezing.
